But in all seriousness... it seems to be a rather unfortunate reality of using FREE email service, that the actual level of privacy afforded to you is minimal. Russia has a very stringent set of anti-extremism laws that curb free speech big time. If your content is labeled extremist, it has to be taken down by an ISP via a swift court order. Note that the "court" is either a single judge or a small panel of judges making the decision. Under that set of laws.
The hosted paid services like Google Apps is another matter all together. There the privacy expectation should be extremely high... but who knows if that's really true.
Because, you know, routine software updates is just what the doctor ordered for on-demand installation of backdoors.
That said, it's quite likely that such malicious behavior would be detected by somebody.
